Abstract
A gate drive circuit includes a plurality of driving stages. An n-th (‘n’ is a natural number) driving stage includes a pull-up part, a carry part, a first pull-down part, a first pull-up/down control part and a second pull-up/down control part. The first pull-up/down control part applies a first power signal of an ON voltage to a control terminal of the pull-up part in a forward direction mode, and applies the first power signal of a second OFF voltage to a control terminal of the pull-up part in a reverse direction mode. The second pull-up/down control part applies a second power signal of the second OFF voltage to the control terminal of the pull-up part in the forward direction mode, and applies the second power signal of the ON voltage to the control terminal of the pull-up part in the reverse direction mode.
